Derry Bold - Chrome Thermostatic Radiator Valve & Lockshield Straight 10mm

Control radiator warmth with greater precision

The Derry Bold Chrome thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its straight 10mm fitting and liquid sensor combine practical connection design with automatic thermostatic response as the room temperature changes.

Why choose these radiator valves?

• Take more control of individual room comfort: The valve automatically alters hot-water flow through the individual radiator in response to the room temperature and selected setting.
• Avoid heating a room more than you need: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Give the heating system extra protection from freezing conditions: The frost setting provides a safeguard for very cold conditions by allowing the valve to open slightly when temperatures fall sufficiently low.
• Finish both sides of the radiator with one set: The set includes the TRV and matching lockshield together, giving you both radiator valves in one coordinated purchase.
• Use a fitting designed around your pipe direction: The straight format is suited to aligned pipework and radiator connections, avoiding an unnecessary change in direction.
• Choose a heating level that suits the space: The multi-temperature head lets you select different heating levels to suit how much warmth the room needs.
• Benefit from automatic response to changing room temperature: The liquid sensor responds to changes in surrounding temperature to operate the thermostatic mechanism automatically.
• Choose a finish that complements the installation: The modern valve shape keeps the installation looking clean and contemporary. In polished & un-lacquered Chrome, the set can be matched deliberately with the radiator finish or used as a contrasting detail.
• Get extra peace of mind after fitting: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
